GEORGE H. BISHOP, OF LAWRENGEBURG, INDIANA.

TROWEL HANDLE.

SPECIFICATION forming part of Letters Patent No. 747,036, dated December 15, 1903.

Application filed August 31, 1903. Serial No. 171,448- (No model.)

To (LZZ whom, it may concern:

Be it known that I, GEORGE H. BISHOP, a citizen of the United States, residing at Lawrenoeburg, in the county of Dearborn and State of Indiana, have invented certain new and useful Improvements in Trowel-Handles; and I do declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of this invention is to provide a simple, reliable, and efficient construction of tool-handle which will admit of the use of cork or cork composition or other like composition grips without liability of the grips becoming readily broken or otherwise injured from service or cracking from pressure due to imperfect connection with the shank or tang of the handle.

In the accompanying drawings, Figure 1 is a perspective View of a trowel embodying my invention. Fig. 2 is a longitudinal section through the handle thereof. Fig. 3 is a crosssection on line 3 3 of Fig. 2; and Fig. at is a View similar to Fig. 2, showing a modified form of handle.

Referring to the drawings, 1 indicates a trowel of usual shape, consisting of the blade 1 and the handle, the latter consisting of a supporting member 2 and grip 3. The supporting member 2 is carried by a rib or foot-,

piece 4, which extends longitudinally of the blade between its edges and is riveted or otherwise secured thereto.

My invention resides in a peculiar construction of the supporting member 2 and grip 3 whereby a grip of cork, cork composition, or composition of like character may be employed in lieu of the ordinary wooden grip without liability of cracking or breaking.

Thesupporting inembercomprises theshank proper, 5, which springs vertically from the rib or foot-piece, the rearwardly-extending right-angular tang 6, and the tenon 7, forming the terminal of the tang. As shown, the tang 6 is of angular form and is provided with a depending \l-shaped key or feather S,which terminates a short distance forward of the rear end of said shank and forms an abutting shoulder 9. The tenon 7 projects some distance rearwardly of this shoulder in the plane of the foot-piece 4, and is of reduced dimensions and may be of cylindrical or other form. The grip 3 comprisesin its construction a core 10, of wood or metal,'and a grip 11, surrounding said core. This grip 11 is made of cork, a composition containing cork, or some other suitable composition adapted to form an effective gripping-surface.

The forward end of the core 10 is provided with a socket 12 to receive the tang 6 and with an intersecting groove or recess 12 to receive the key or feather S, said recess corresponding to the form of the key, so as to form therewith a lock to hold the core from rotation. At its forward end the lower portion of the core is notched at 13' to receive theupper extremity of the shank 5 and so as to allow the front surface of said shank to lie flush with the front surface of the core. The core 10 is further provided with a reduced bore or passage 14., receiving the tenon 7, which latter is designed to project slightly beyond the rear end of the core and to be threaded for the reception of a nutor to be upset to provide a rivet-head to hold the core in position against longitudinal movement.

It will be observed that the tang 6, with its key or feather 8, looks the core firmly inplace against rotation, and the shank 5 and shoulder 9 cooperate to prevent any forward move ment of the core upon the tang and tenon, so that working of the core while the tool is in use cannot possibly take place. 7 gives the necessary rear support for the core and grip and need not be of so large a dimension as the tang, as the latter affords the required locking connection and braces the grip at the front, where the strain comes in manipulating the trowel.

If desired, the grip 11 may entirely cover the peripheryvof the core and be notched at its forward end, as indicated at 13, to receive the shank 5, or the forward end of the core may be formed into an external rim or shoulder 15, against which the forward end of the grip 11 may abut. The latter construction is clearly shown in Fig. l.

The great advantage of my invention is that by the use of the core a grip of cork, cork composition,or other substance unable to sustain severe strain may be employed with- The tenon out the same cracking or becoming broken or otherwise injured with ordinary care in the usual service of the tool. A grip of cork is deemed preferable to one of any other material in that it affords a surface which may be readily gripped and which does not become slippery or otherwise objectionable in use. The object of making the feather of V form and, as shown, with practically a knife-edge and with the shoulder 9 is to adapt the same to easily enter the groove or recess 12, thus allowing the core to be slipped into position without liability of cracking or splitting in case there are any slight obstructions to the passage of the tang into the socket 12. The core itself sustains the pressure falling upon the grip, and thus prevents the latter from without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to Without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

A tool-handle comprising a shank having a tang extending at an angle thereto, a core upon the tang, and a grip upon the core, the core being keyed to the tang and both core and grip keyed to the shank, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

GEORGE H. BISHOP.
